The Additel 901B Low Pressure Test Pump is a portable, hand-operated device designed to generate precise pressures ranging from -6 psi (-0.4 bar) to 6 psi (0.4 bar). Weighing only 3.5 pounds (1.6 kg), it is both lightweight and robust, making it ideal for field and laboratory applications. The pump features a high-quality screw press that allows for fine pressure adjustments with a remarkable resolution of up to 0.1 Pa (0.001 mbar). Its isothermal bellows chamber minimizes the effects of environmental temperature fluctuations, ensuring exceptional stability during calibrations. Additionally, the 901B is equipped with two hand-tight connectors, facilitating quick and tool-free connections without the need for PTFE tape or wrenches. This design eliminates the use of non-returning valves, reducing maintenance requirements and enhancing reliability. The Additel 901B is an excellent choice for low-pressure calibration tasks, offering precision, stability, and user-friendly operation.
